DOWEL-PIN AND FASTENER FOR TRUNKS.

i Application filed February 29, 1904.-. Serial No. 195,801. (No model.)A

To all whom it may concern:

Be itknown that LOTTO RANGNOW, a citizen of the United States, residingat Philadelphia, in the county of Philadelphia and State ofPennsylvania,have invented certain new and useful Improvements` in Dowel-Pins andFasteners for Trunks, of which the is a specification.

My invention relates to an improved dowelpin and fastener for trunks,and relates to that following classof dowel-pins in which the same aredivided into two members, one of said members being carried by the lidof the trunk and havingformed thereon a pin, and upon the other `of aspring to hold the said parts locked.

A further object of my invention is to provide a means of unlocking thefastening mechanism and of causing the members to spring apart andremain unlocked until the lid of the trunk is lifted.

Referring to the drawings, Figure l is a' front elevation of atrunk,'showing my improved dowel-pin and fastener applied thereto. Fig.2 is a vertical sectional view as.. on line 2 2, Fig. l, on a largerscale. Fig. 3 is a similar-view showingthe parts in a differentposition. Fig. I isa sectional View on line 4 1l, Fig. 2. Fig. 5 is aperspective view of one of the parts-detached.

In the drawings, A refers to the lid of a trunk, and vB the body ofatrunk. To the lid A is attached the upper m'ember C of the' dowel-pin,carrying a dowel-pin. C', having formed on its lower end a shoulder c,projecting rearwardly ortoward the trunk. A handle or lift C2 also formsa part of the upper member C. The upper member C is attached to thelidfof the trunk by means of rivets c a and c c. The rivets ce passthrough the lid of the trunk, while the rivets d a only pass through thevalance-strip A2, which is secured to the lid by rivets c3. The objectof this is to hold u1@ down-pin in a vertical 11neficient flexibility toallow it to be forced over a projection in the fastening mechanism, asdescribed later; The lower member D, which is larged portion d, forminga socket to receive the dowel-pin C.' As shown in Fig. 4, said lowermember D is provided with flanges D2 on its outer edges, which form arecess adapted to receive a plate E. Apel-tures are formed in the saidplate E, which aline with apertures in the lower member to receiverivets f, by which the plateEand the lower member D arerigidly secured'to the body of the trunk. Within the socket formed in the enlargedporfrom a pin d2, which passes through the plate E and holds said plateand the lower member D together. On the said plate E is a struckupportionv E', which forms a projection E2, which projects forwardly toengage the shoulder c on the doWel-pin C. The said Struckup portion Eforms a cam-surface E3, which forces the pin C out of the vertical linewhen entering the saidv socket. A spring G is held within the saidsocket by means of said pin d2. This spring is only in action when thedowelpin C is entering or leaving the socket, as shown in Fig. 3. Whenthe dowel-pin C has dropped into place over the projection E2, as shownin Fig. 2,`the springG will be released and will notV exert any pressureagainst the said dowel-pins, which will be held in engagement with thesaid projection by means of the rivets and valance-strip carried by thelid A. `Should the Valance-strip A2 fail to hold the dowel-pin C in itsproper verticalposition, the said spring G will prevent it from becomingdisengaged from the projection E2. A latch Fis pivoted on the said pind2. The lower end F of said latch has a depression formed therein forthe lingers, and its opposite end F2 projects into the center of thesocket, so as to engage the doWel-pin C. l Whenit is desired.. to openthey trunk, the lower end of the latch Fis forced in, which causes itsother end, F2, to bear against the dowel-pin C' and force it backagainst the action of the spring Gr until the shoulder c is and to givethe lower end of the dowel-pin sufv secured to the body of the trunk,has an en` tion d is a web d', having projecting there-l drawn out ofengagement with the projection E2, as shown in Fig. 3, when it will beforced upwardly by the action of the spring Gr and the latch F to theposition shown in dotted lines in Fig. 3. The lower end of the dowelpinC is provided with curved surfaces which facilitate the movement of thedowel-pin C/ into and out of engagement with the di'erent parts.

The lower member D is providedA with downwardly-projecting walls H and Hto protect the latch from any accidental blow. It will be seen that in'my improved dowel-pin and fastener the parts Will remain locked withoutthe action of any spring. The spring is only in action when thedowel-pin is being forced into place or being forced out of engagementwith the projection by means of the latch, and therefore it will notlose its vitality as it would if under constant tension. Having thusdescribed my invention, I claim and desire to secure by LettersPatent-V 1. The combination of an upper member carrying a dowel-pin witha shoulder formed thereon, a lower member having a projection to engagesaid doWel-pin, a latch to disengage said dowel-pin, and a springadapted to force the said doWel-pin from said lower member,substantially as described.

2. The combination of an upper member, a dowel-pin carried by the same,a shoulder formed on said dowel-pin, a lower member having a socketformed therein, a plate having a projection formed thereon, a pin securing said plate to said lower member, walls projecting downwardly fromsaid lower member, a latch pivoted on the latter pin and a springsecured in said lower member, substantially as described.

3. rIhe combination of an upper member, carrying a dowel-pin having ashoulder formed thereon projecting rearwardly, a lower member having asocket formed therein, a plate to complete said socket, Said platehaving a projection extending forwardly, a latch to disengage saiddowel-pin from said projection, and a spring to force said dowel-pinupwardly when acted upon by said latch and also to prevent theaccidental disengagement of said dowel-pin and said projection,substantially as described.

In testimony whereof I aiix my signature in presence of two witnesses.
